WILLIAM KRUTZSOH, OF DAYTON, OHIO, ASSIGNOR TO THE BUCKEYE IRON AND BRASS WORKS, OF SAME PLACE.

MEAL-CAKE-MOLDING BOX.

fiPEC'IFICATION forming part of Letters Patent No. 361,879, dated April 26, 1887. Application filed July 1, 1886. Serial No. 206,846. (No model.)

To all whom it may concern:

Be it known that 1, WILLIAM KRUTZsoH, a citizen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented new and useful Improvements in Meal-Cake-Molding Boxes, of which thefollowing is a specification.

In the manufacture of linseed and other oils the meal from which the oil is to be expressed is inclosed by a sack or piece of textile material and arranged in a molding-box, which is then introduced into a press or former and su jected to a preliminary pressure to form the meal intoa compact cake, after which the formed cake is placed in an oil-press to extract the oil from the previously-formed meal-cake. It is a very difficult matter to remove the formed cake after the pressing operation, owing to the fact that the cake adheres or sticks to the sides of the box or cake-former.

To avoid this is the essential object of my invention, which I accomplish by constructing ble or movable with reference to each other, whereby when the box is removed from the press its sections are or can be separated the one from the other, thereby freeing the sides of the box from the side edges of the formed cake.

The invention also has for its object to provide novel means whereby the shape of the cake and the quantity of the meal deposited in the molding-box or cake-former may be varied at will, which I accomplish by providing at each end of the molding-box a removable and replaceable block or plate, as more fully hereinafter described.

The invention is illustrated by the accompanying drawings, in which Figure 1 is an end elevation of the moldingbox or cake-former; Fig. 2, alongitudinal section taken on the line 00 x of Fig. 1, showing the meal-pan partly drawn out from the mold ing-box; Fig. 3, a plan view of the moldingbox, showing the sections separated and the meal-pan removed; Fig.4, a transverse sectional view on the line 3 y of Fig. 6; Fig. 5, a front elevation of Fig. 6; Fig. 6, aplan view of Fig. 5, showing the parts in position for filling the molding-box; Fig. 7, a detail sectional view showing the meeting edges of the sections of the molding-box beveled 5 Fig. 8, a detail crosssectional view on the line 2 z of Fig. 10, showing a modification in the construction of the flaps, hereinafter referred to; Fig. 9, a longitudinal sectional view of one of the modified flaps; Fig. 10, a plan view of Fig. 8; and Figs. 11 and 12, detail views of a modification, hereinafter explained.

In order toenable those skilled in the art to make and use my invention,Iwill now describe the same in detail, referring to the drawings, where the letters A A indicate the two sections of the moldingbox, having attached vertical walls a a. The front section, A, is provided with a suitable handle, D, and is provided at its ends with T-shaped grooves engaging T- headed tongues or guides L L, which are fastened to the wheel-carrying brackets B B by the T-headed bolts n n.

The brackets carry wheels 0 O, mounted on spindles b b, and the rear section, A, of the molding-box is rigidly secured to the wheelbrackets, all in such manner that the front section, A, can slide to and from the rear section, A, to an extent limited by the stops F ande, secured, respectively, to the front section and one of the wheel-brackets. The box-sections are shown separated in Fig. 3, for clearing its sides a a from the sides of the formed meal-cake. I prefer to bevel the longitudinal meeting edges of the box-sections, as in Fig. 7, so that any meal which may gain access between such meeting edges will fall away and not lodge between them to prevent the perfect closing of the box-sections. To some suitable part of the press, for instance, as in my Letters Patent No. 296,186, dated April 1, 1884, are secured two standards, h h, to which are hinged by arms 9 g the end flaps, G G, each of which comprises a hollow metallic casting having an inner beveled or other shaped overhanging edge, r, for the purpose of causing a little less meal tobe deposited at the ends of the cake. The edges Z l of the flaps are of such shape that when the flaps are turned down, as in Fig. ,6, such edges form a trackway, in connection with the upper edges of the'sides a a of the molding-box, for the travel of the bottomless meal-box to supply the meal to the molding-box, substan- IOU tially as disclosed in my aforesaid patent.

The two flapsat the rear are rigidly unitedby a crossbar, f, secured by screws m rawhile the fronts of the flaps are provided with outwardly-proje'cting arms K K, to which are secured the ends of the handle-bar H, for raising and lowering the two flaps. The fronts of the flaps are also provided with lugs k, extending toward each other for engaging the ends of the front side, a, of the box, Fig. 4, which lugs, in connection with the cross-bar f, serve to hold the two sections of the molding-box together while it is being filled with meal. The meal-pan d, Fig. 2, is provided with a handle, 0, by which to manipulate it.

In order to enable the operator to vary at will the shape of the cake and the quantity of meal deposited in the molding-box, I provide the flap-castings Gr, Figs. 8, 9, and 10, with wooden or other plates or blocks G,which are detachably secured to the castings by screws or otherwise. If it is desired to place more or less meal in the molding-box, or to change the shape of the top surface of the cake, one or both of the plates can be removed and planed or fashioned to the required shape and size, after which such plate or plates are replaced in proper position on the casting, or new plates or blocks may be substituted, if desired. v

I do not wish to be understood as confining myself to any particular construction of parts for effecting the movement of the molding-box sections with reference to each other to release its sides from the sides of the formed cake, as other constructions than those shown will suggest themselves to those skilled in the art. I may dispense with the Wheeled brackets B B and substitute some other contrivance-such, for example, as shown in Figs. 11 and 12, where supporting bars B aresubstituted for the wheeled brackets. In this case the rear boxsection, A, is rigidly secured to the bars B by screw-bolts B while the front box-section, A, is fitted to slide on said bars by a tongueand-groove connection, so that it can moveto and from the rear section, suitable stops being provided to limit the sliding movement. In operation the molding-box sections are closed together by pushing on the handle D, after which the flaps G G are closed down, as shown in full lines, Figs. 4 and 6. f

In practice, meal is drawn from a large kettle, called a heater, into a bottomless box, called a meal-box. This box sits on a stationary platform, which is of the same shape as the flaps shown in Figs. 8, 9, and 10. This platform is in such a position on the pressframe that when the flaps are swung down they form with it and the sides a a a continuous track, on which the meal-box may slide. When the molding-box A A is drawn out from the press, (which I call a former,) it strikes against a stop. Its edges or a are thenin line with corresponding edges on the stationary platform. The pan d is then put in the bottom of the inoldingbox and a cloth laid upon it, the two ends of this cloth hanging downward over the ends of the box and pan. 'Ihle flaps arenow swung down, and they bridge the space between the edges a a and the sta tionary platform. There is now a continuous track, l la a, on which the meal-box may slide entirely across the molding-box. When it crosses the latter, it deposits its meal on the aforesaid cloth and strikes off the upper surface-to the shape of the top surface of the flaps. It is then shoved back onto the stationary platform, the flaps swung'up, and the two ends of the cloth brought up and folded over the top of the meal, the ends of the cloth meeting or overlapping in the center. The moldingbox is then shoved into the press (called a former and subjected to amoderate pressure. This press is not intended to extract the oil, it being only to form the loose meal into a compact cake. A number of these cakes are put into oil-presses and subjected to a very high pressure. It is this second pressure which extracts the oil. to the preliminary pressure, the molding-box is drawn out from the former. The act of drawing it. out also frees the cake from the sides of the molding-box, as before explained.

After being subjected I The cake is then removed from the moldingbox and inserted in the large press. The pan is put back in the molding-box, and the same set of operations repeated indefinitely.

Having thus described my invention, what I 7 claim is 1. A meal-cake-molding box composed of two sections, one stationary and the othermovable laterally in astraight line to and from the stationary section to disengage the walls of the box from the edges of the formed cake, substantially as described,
